I wonder if it is possible to read a spreadsheetML file and convert it to an .xls.
I noticed the following on Wiki:
//Creating an Excel object
Excel excel=new Excel();
//Calling Open method of Excel object to open SpreadsheetML file
//Save in default Excel2000 format
My problem is that the first part (C#) is not possible via Java?
I can not find the open(String fileName, FileFormatType format) method in the java library…
